Title: Analog signal delay circuit
Inventor: TACHIKAWA KENJI
IPC: H03H11/26
Filed: 1987-08-20
Abstract: PURPOSE:To prevent the fluctuation of a signal level and the deterioration in S/N due to noise by delaying a digital signal stored by a storage means, then outputting the result to a digital/analog signal conversion means. CONSTITUTION:An analog signal delay circuit consists of, e.g., an analog digital converter 1, a digital analog converter 2 and a memory 3 being a storage means. The memory 3 has a memory area Mn (n is 0, 1, 2, 3-n) of unit capacity corresponding to a shift register 4a. Then the data is transferred sequentially from a memory area M0 to a memory area M1 by each unit capacity of the shift register 4a. Then the digital signal stored in a last memory area Mn is sent to a parallel signal circuit 4b and its delay time depends on the capacity of the memory area Mn. The digital signal outputted in parallel is converted into an analog signal by a digital/analog converter 2, and outputted as a delayed analog signal from a terminal 3a. Thus, the mass-product component relating to the data processing technology is utilized.

Patent JP-H10116253-A (JP)
Title: Multiprocess system executing synchronous operation
Inventor: HAGERSTEN ERIK E
IPC: G06F9/46
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To complete an asynchronous operation one or several operation before the last operation globally by delaying subsequent transactions by a system interface in a node until an unprocessed coherency activity is completed. SOLUTION: A system interface logic block 62 uses an ignorance signal 70 so as to effectively operate together with ordered restrictions imposed by the output queue/input queue structure of an address controller 52. When a transaction is supplied onto an address bus 58 and the system interface logic block 62 responds to detect the execution of a remote transaction, a logic block 62 asserts the ignorance signal 70. When the ignorance signal 70 is asserted to a certain transaction, the address controller 52 suppresses the storage of the transaction in an input queue 74. Thus, subsequent transactions are delayed from a processor until an unprocessed coherency activity is completed.

Title: Beam deflector
Inventor: ANTOON MATSUTERIN
IPC: B23K26/082
Filed: 1985-09-20
Abstract: The deflection of a light beam in two mutually perpendicular directions ensues by rotating two spindles which are hinged to a single deflection mirror and whose axes reside perpendicular to one another. The first spindle is hinged to the deflection mirror via a fork joint such that the trunnion axis of said fork joint and the axis of the first spindle are perpendicular to one another. The second spindle is hinged to the deflection mirror via a turning arm and a dog secured to the backside of the deflection mirror. So that the two spindles can be turned independently of one another, the dog is guided in the turning arm so as to be freely pivotable around the axis of the first spindle. The dog is preferably guided in a slot of the turning arm. Apparatus equipped with only a single deflection mirror for the deflection of a light beam in two mutually perpendicular directions are usefully employed in laser labeling.

Abstract: PURPOSE:To enable to input to an existing data processing system as it is and improve economy by making outputting interchangeable with existing data format for a form which consist only of numeral, English character, Katakana (Japanese syllabary in square type) and symbol data. CONSTITUTION:When a form 3 is put in, it is carried to a photoelectric converting section 6. Here, the space of the form 3 is converted to a digital pattern and stored in a memory 5. A cutting out section 7 cuts out the character pattern one by one from the space pattern basing on due form information and stores in the memory 5. A recognizing section 8 makes recognition using character pattern and due form information and writes the result in the memory 5 as an internal code. A controlling section 2 converts output data format using the result of recognition and due form information and outputs to an outputting device 9. In this case, nemeral, English character, katakana and snymbol data (NAKS) are converted to EBCDIK code of one character one byte and outputted and can be inputted to existing data processing systems as it is. Thus, economy can be improved.
